Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing and specific implementation
Example, the present invention is described in detail.It should be appreciated that specific embodiment described herein is used only for explaining the present invention, and
It is not used in the restriction present invention.
The seal wire and its manufacturing method that can be set the present invention relates to a kind of flexibility are used to assist conduit or other devices
Tool is introduced into lumen of a body vessel, in order to diagnose or treat disease.
The seal wire that the flexibility can be set is made of single metal wire, is provided on the outer peripheral surface of the wire recessed
Slot, the groove are made of by way of permutation and combination multiple chase units.
Embodiment 1
As shown in Figure 1, multiple chase units 2 are arranged into helical structure, the shape of the chase unit 2 is straight
It is linear.Multiple chase units 2 be it is end to end, final multiple chase units 2 form one in the outer surface of wire 1
Helix.To make the flexibility of the seal wire reach necessary requirement, the screw pitch of adjustable helix, in the smaller area of screw pitch
Domain flexibility is better.
Embodiment 2
As shown in Fig. 2, multiple chase units 2 are arranged into double thread shape structure, the shape of the chase unit 2
For linear, multiple chase units 2 are intervally installed, and the depth of groove of the chase unit 2 is greater than the wire 1
Radius, less than the diameter of the wire 1.The double thread shape structure is in mirror image relative to the axial cross section of wire 1
It is symmetrical arranged, when being separated by 180 degree and existing simultaneously chase unit on the symmetrical axial position of wire 1, opposite is recessed
Then mutual connection forms fine crack to slot unit；There are three kinds of states in the axial direction of the wire 1 described in this way: not cutting, single groove
The fine crack that unit, opposite chase unit are formed.By changing these three states in ratio, Ke Yishe present on wire 1
Determine the flexibility of seal wire.
Embodiment 3
As shown in figure 3, multiple chase units 2 are arranged into multiple cyclic structures, the shape of the chase unit 2 is
Linear, multiple chase units in the same ring structure are end to end each other, finally the shape on wire outer peripheral surface
At the slot of multiple annulars.The face that the cyclic structure is formed is the plane being parallel to each other, and mutual spacing is equal.
The recess width of the chase unit is fixed, and is less than the diameter of the wire 1.The depth of groove of the chase unit 2 is not
Together, and less than the radius of the wire.The deeper region of depth of groove, the flexibility of wire is better, adjusts chase unit 2
Depth can set the flexibility of seal wire.
Embodiment 4
As shown in figure 4, multiple chase units are arranged into multiple cyclic structures, the shape of the chase unit is song
Linear, multiple chase units 2 in the same ring structure are end to end each other, finally the shape on 1 outer peripheral surface of wire
At multiple wavy annular grooves.The face that the cyclic structure is formed is the curved surface being parallel to each other, and the spacing between curved surface is equal.
The depth of groove of the chase unit 2 is fixed, and is less than the radius of the wire 1.The recess width of the chase unit 2 is not
Together, and less than the diameter of the wire.The wider region of width, the flexibility of wire is better, therefore adjusts chase unit 2
Width can set the flexibility of seal wire.
Embodiment 5
As shown in figure 5, multiple chase units 2 are arranged into multiple cyclic structures, the shape of the chase unit 2 is
Linear, multiple chase units 2 in the same ring structure are intervally installed, and the chase unit 2 is hanging down
Directly on the section of wire axial direction be in " D " font.The face that the cyclic structure is formed is the plane being parallel to each other, multiple planes
Between spacing be different.The smaller region of spacing between multiple planes, the flexibility of wire 1 is better, therefore adjusts
The spacing of chase unit 2 can set the flexibility of seal wire.
Embodiment 6
As shown in fig. 6, multiple chase units 2 are arranged into multiple cyclic structures, the shape of the chase unit is
Linear and curved combination, multiple chase units 2 in the same ring structure are end to end each other, ultimately form
Continuously " Ω " shape.The face that multiple cyclic structures are formed is the plane being parallel to each other, and the spacing between multiple planes is
It is identical.The design of this groove structure can make the outer surface of wire 1 form the similar structure buckled, manufactured in this way to lead
Silk can prevent local excessive to be bent and generate and fracture in bending.
Those skilled in the art can pass through shape, the depth and width, arrangement side of change chase unit 2 mentioned above
It is one or more in these variables of formula, pitch density, to change the flexibility of seal wire, and then reach necessary requirement, groove list
The combination of member is very more, will not enumerate embodiment herein.
In order to reduce the frictional force on seal wire surface, improves the interaction between instrument, improve the tracking of seal wire in the blood vessel
Property, it may be provided with coating in the outer surface of the seal wire, the coating is divided into hydrophilic coating and hydrophobic coating two major classes, hydrophilic painting
Layer can attract hydrone to be formed on its surface " gel " surface, reduce seal wire in the blood vessel pass through resistance；Hydrophobic coating is logical
It is often high density PTFE coating, it is possible to reduce the frictional force of microtubular and seal wire.
The seal wire that above-mentioned flexibility can be set is manufactured using following steps:
1) prepare wire of the diameter between 0.1~3.0mm.
2) mode being cut by laser carves groove on the outer peripheral surface of the wire, and the groove is by multiple grooves
Unit is constituted by way of permutation and combination.
Laser cutting means have become the common processing method of medical instruments field at present, due to the laser of different model
The equipment difference of cutting machine, specific cutting parameter can be also slightly different, the type of laser of the laser cutting machine that our company uses for
Femtosecond laser, laser energy 1000mW-16000mW, laser pulse frequency 100-500KHZ, those skilled in the art can
The chase unit is realized by adjusting the parameter of laser cutting machine, it can is adjusted according to the depth and width of cutting
The intensity of laser.Therefore specific parameters of laser cutting and detailed processing method, those skilled in the art can be according to existing skills
Art is selected, and the present invention repeats no more.
Finally it should be noted that the foregoing is merely preferred embodiments of the invention, not to limit this
Invention, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in this hair
Within bright protection scope.
